Macadam-shaped vulcanic ash lightweight ceramsite with air purifying function

Abstract

The invention discloses macadam-shaped vulcanic ash lightweight ceramsite with air purifying function. The main points of the technical scheme are as follows: ingredients are composed of attapulgite clay powder, vulcanic ash, activated clay waste residue, white carbon black, activated aluminium oxide, sodium aluminate, hollow beads, sodium dodecyl sulfate and scrubbing vulcanic ash photocatalyst spraying liquid, etc. The ingredients successively undergo the following processes: stirring, extruding and pelletizing, drying, crushing, screening, calcination, thermal insulation, screening, soaking, drying, screening, sealing and packaging. Finally, the macadam-shaped vulcanic ash lightweight ceramsite with air purifying function is prepared. The macadam-shaped vulcanic ash lightweight ceramsite with air purifying function has characteristics of large specific surface area, low bulk density, good lightweight strength, high hygroscopicity, superior adsorption and purifying properties, is applicable to rooms, furniture cabinets, vehicles, ships or other buildings, and is used for adsorbing and degrading pollutants such as formaldehyde, ammonia, benzene, TVOC and the like so as to achieve the purpose of long-term air purification.

Description

technical field [0001] The invention relates to ceramsite, in particular to a gravel-shaped volcanic ash lightweight ceramsite with the function of purifying air. Background technique [0002] There are several types of air purifiers currently available on the market: adsorption-type air purifiers, masking-type deodorizing products, and decomposing-type deodorizing products. Adsorption-type air purifiers are purification products that use activated carbon, bamboo charcoal, molecular sieves, minerals and other materials to remove pollutants through physical adsorption, chemical adsorption, catalytic oxidation and reduction; masking-type deodorant products use the fragrance of aromatic hydrocarbons to cover the air. In fact, many air fresheners do not remove the odor, but just cover up the odor with a fragrance; decomposing air purification products are relatively rare in the market.
